implements as ditch fillers, graders, planers,

scarificrs, rooters, scoops, snow plows, etc.

Attachments which consist of a frame car ricd at one end by thedifferential housing of a standard tractor and at the other end by theforwardly shifted front axle assembly of the tractor, and which have atool mounting located in an intermediate position, are

in common use for performing such operations as scarificing, grading,etc. In such machines, the forewheels always precede the tool and thenecessary superposed'tool" o thrusting weight is obtained by providing acomparatively heavy and therefore expensive foreframe which, of course,adds to the cost of the machine. In addition, the general arrangement ofsuch attachments may be objectionable when performing certam classes ofwork, and the relative posi-v tions of the steering wheels and tool areobviously disadvantageous when the machineis being employed for suchvpurposes as ditch filling, snow plowing, and the like.

In order to obviate confusion of terms during the course of thisdescription and in its appended claims, the rearwheels of the standard.tractor employed.in-;my invention which are mounted on the drive shaftsextending from the differential housing will be designated as the drivewheels of such tractor, and the wheels which are mounted on the frontaxle of such tractor 40 will be designated as the steering wheels.The'terms forwardly and rearwardly as employed in this description andin the appended claims will have reference to the respective ends of theimplement carrying frame only, and that end of thetractor which isnormally itsfront end will be designated as its steering end, and thatend of the tractor which is normally called its rear end will bedesignated as its driving chine illustrated in Fig. 1.

end.

My invention, with the object of providmg a more generally satisfactorytool carrymg attachment for use in combination with standard tractors,contemplates an arrangement consisting of a tool supporting'frameworkadapted to have its. rear end carried by the steering wheels'of thetractor and its forward end mounted on the tractors differentialhousing, the tool being positioned at the'forward end of theimplement-carrying frame and proximate to the driving wheels of suchtractor in order to afford adequate weight for resisting vertical andlateral tool thrust and the machine as a whole being adapted fortravelling in a direction which would be effected by having "suchtractor operate in normal reverse gear.

In this form of construction, the tool al- "waysprecedes the drivingwheels, and the tractors normal weight is employed to directlycounteract and oppose tool thrust as well as to positively hold suchtool in the selected operating position. These features are particularlyuseful in machines intended for heavy work, the practically directconnection between the tractors differential housing and the toolpermitting a maximum pushing effort without necessitating a veryelaborate frame Work, and the'position of the tool adapting the machineto functions which can not be conveniently effected by attachments inwhichthe tool is carried rearwardly of the steering wheels and forecarriage. To the accomplishment of the foregoing and related ends, saidinvention, then, consists of the means hereinafter fully described andparticularly pointed out in the claims.

The annexed drawings and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but one of variousmechanical forms in which theprinciple of the invention may be used.

In said annexed drawings:

Fig. ,1 is a side elevationalview of a standard tractor equipped withthe tool carrying attachment provided by this invention; and Fig. 2 is aplan view of the ma- In the drawings, my invention is shown inassociation with a standard tractor and comprises two main frame members1 which, towards their forward ends, are directed upwardly and providedwith perches 2, these pe ches having concave faces and co-acting withthe complementally shaped parts 3 1n holding the frame in assembledrelation to the differential housing 4. Towards their rearward ends, theframe members 1 converge and are adapted to form a mounting for thesteering wheel tractor axle 5, such axle together with its wheels andsteering mechanism having been shifted from its normal position andreplaced by a suitable yoke 6 which is secured to the frame members.

Intermediate the rear steering wheels 7 and the steering end of thetractor, suitable control apparatus and a station for the operator areprovided; such station, if desired,

being covered by a protective top. The

steering gear consists of a wheel 8 which, through suitable mechanismenclosed by the casing 9, is adapted to operate an arm 10, this armconnecting with a rod 11 which is attached to a bell crank 12 mounted onone of the wheel spindles, a transverse tie rod 13 serving tointerconnect the wheels in the usual manner. The steering gear isdesirably so arranged that the normal wheel movements will produce thenormal changes in the direction of travel; in other words, clockwiseturning of the steering wheel 8 (Fig. 2) will rotate the wheels 7 in acounterclockwise direction, but the direction of mo.- tion of themachine as a whole will be as usual, i. e., to the right. Similarly,counterclockwise turning of the wheel 8 will cause the machine toproceed to the left although the wheels 7 will, of course, be turned ina clockwise direction.

In a position approximately above the differential housing 4, the framemembers 1 are provided with a transverse part 14 which is braced by theinwardly extending pieces 15 and centrally carries an oscillatablethrust sleeve 16. The sleeve 16 is adapted to receive one end of a shaft17 which has a collar 18 and is preferably encircled by a compressionspring 19, this spring bearing against the outer of the two eye membersattached to a beam 20 and forming with the shaft 17 and the collar 18(which in addition to forming a bracing for the spring also preventsseparation) a yieldable connection between such beam 20 and the sleeve16. At its forward end, the beam 20 carries a revoluble circle 21 which,as best shown in Fig. 2, is provided with depending arms 22 and isrearwardly guided by a part 23. The circle 21 may be revolved around itscenter 24 and locked in any selected position by a pin 25, this pinbeing adpated for reciprocation in an opening 26 provided in itsmounting 27 and having a lower extremity for engaging in any one of anarcuate series of holes formed in the circle rim. A rod 28 which isdesirably extended back to the operators station is connected with alever 29 arranged for manipulating the pin 25 when changing the circlesetting.

Secured to the forward end of the beam 20 is a transverse bar 30 whoseprojecting ends are universely connected to the hanging screws 31 bycouplings 32 which have ball shaped extremities positioned within theboxes 33. The upper portions of the screws 31 are mounted in nuts 34which may be revolved by gears 35 meshing with similar gears 36, theformer constituting part of the nuts 34 and the latter formed on shaftswhich extend through one of the gudgeons 37 and connect with shafts 38adapted to be revolved by hand wheels 39 from the operators station. Thenuts 34 and the gears 36 are enclosed by casings 40 which have gudgeons37 journalled in the ends of the forks 41, such forks being revolublymounted on the ends of a shaft 42 which is supported by brackets 43attached to the ends of the frame members 1. Due to the fact that thehandwheels 39 are most conveniently revolved in opposite directions whenraising or lowering the scraper blade 44 or other tool,

one of the nuts 34 is desirably reversed so thatits gear 35 meshes withthe top instead of the bottom of the gear 36, this permitting of themost convenient hand wheel motion and yet simultaneously raising orlowering both ends of the blade in the desired manner. The blade 44 maybe removably and reversably attached to the moldboard 45 which ispivoted to the arms 22 as at 46 and adjustably attached as at 47 Whenequipping a tractor with the attachment provided by this invention theusual transmission or differential gearing may be reversed so that thethree ordinarily provided variations in ratio will be available when thetractor is moving in a direction opposite to its normal forwarddirection, and the one normal reverse speed available for motion in adirection opposite to that in which said speed is normally effective. Inother words, the normal forward direction of travel of the tractorbecomes the reverse direction, and the normal reverse direction becomesthe forward direction.

From the above description and explanation, it will be apparent that myinvention provides a comparatively simple attachment for the purposespecified; a machine which can be inexpensively constructed from astandard tractor and which is adapted for performing numerousoperations; a design which employs the normal tractor weight to the bestadvantage; and which, in addition to its other desirable features, makesconversion of the standard tractor to a more versatile machine, arelatively easy matter to accomplish. It will be understood that withappropriate modifications in dimensions my improved attachment can bereadily adapted to use in combination with differently constructedtractors, and that the forwardly positioned thrust members are suitablefor many purposes, including the moving of a great variety of tools,implements, etc. It will also be understood that while ny invention hasbeen described as an attachment, it may be embodied in a special machineand its different features retained in substantially their describedform, these presenting the advantages explained regardless of whetherthe power unit is a standard tractor or an integral part of the machine.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any of the following.claims or the equivalent of such stated means be employed.
